miR-146b-5p promotes duck Tembusu virus replication by targeting RPS14
Duck Tembusu virus (DTMUV), belonging to the Flaviviridae family, is a major virus that affects duck health in China. MicroRNAs (miRNAs) play an important role in viral replication. However, little is known about the function of miRNAs during DTMUV infection. Here, the host miR-146b-5p was found to...

description | Duck Tembusu virus (DTMUV), belonging to the Flaviviridae family, is a major virus that affects duck health in China. MicroRNAs (miRNAs) play an important role in viral replication. However, little is known about the function of miRNAs during DTMUV infection. Here, the host miR-146b-5p was found to regulate DTMUV replication. When DTMUV infected duck embryo fibroblasts (DEFs), the expression levels of miR-146b-5p increased significantly over time. Moreover, the viral RNA copies, E protein expression levels and virus titers were all upregulated when miR-146b-5p was overexpressed in DEFs. The opposite results were also observed upon knockdown of miR-146b-5p in DEFs. To explore the mechanism by which miR-146b-5p promoted DTMUV replication, mass spectrometry, and RNA pull-down assays were employed. Ribosomal protein S14 (RPS14), a component of 40S ribosomal proteins, was identified to interact with miR-146b-5p. In addition, the relative mRNA expression levels of RPS14 gene were negatively modulated by miR-146b-5p. Subsequently, it was found that overexpression of RPS14 could decrease the replication of DTMUV, and the reverse results were also detected by knockdown of RPS14. In conclusion, this study revealed that miR-146b-5p promoted DTMUV replication by targeting RPS14, which provides a new mechanism by which DTMUV evades host defenses and a new direction for further antiviral strategies development. |
